Week 5 - Journal

✨ Step 1: Bringing players to the playground
I gathered all my electronic “players” onto the breadboard: the slide switch, push button, buzzer, white LED, red LED, resistors, jumper wires, and the 5V adapter. Time for the match to begin!

✨ Step 2: The Power Captain (Slide Switch)
The slide switch is the “main gatekeeper.”

• When it’s turned ON, power flows into the system.

• At that moment, the white LED lights up to show that the system is active.

✨ Step 3: The Bell Duo (Push Button, Red LED + Buzzer)
The push button is the “ring” of the bell system.

• When pressed, it sends current to both the red LED and the buzzer at the same time.

• The red LED lights up for visual feedback (helpful for people with hearing difficulties).

• The buzzer makes sound for the regular doorbell effect.

• Both are connected in parallel to the push button, so they activate together.

✨ Step 4: Wiring Logic (Series + Parallel Mix)

• Red LED:

  • Positive leg (long leg, bent) → one side of the push button

  • Negative leg (short leg) → resistor → negative power source

• White LED:

  • Positive leg → slide switch

  • Negative leg → resistor → negative power source

• Buzzer:

  • Positive leg → push button

  • Negative leg → negative power source

So:

• White LED is controlled by the slide switch (power ON indicator).

• Red LED + buzzer are controlled by the push button (doorbell signal).
